Facebook CEO Mark Zuckerberg said this week the company will create an oversight board to help with content moderation. The move is a belated acknowledgement Zuckerberg is out of its depth when it comes to ethics and policy, and comes six months after he first floated the idea of “a Supreme Court … made up of independent folks who don’t work for Facebook.”

The idea is a good one. If carried out properly, a “Supreme Court” could help Facebook begin fixing the toxic stew of propaganda, racism, and hate that is poisoning so much of our political and cultural discourse.

But how would a Facebook Supreme Court actually work? Zuckerberg has offered few details beyond saying it will function something like an appeals court, and may publish some of its decisions. Meanwhile, legal scholars in the New York Times have suggested it must be be open, independent and representative of society.

As for who should sit on it, it’s easy to imagine a few essential attributes for the job: The right person should be tech savvy, familiar with law and policy, and sensitive to diversity. Based on those attributes, here are five people that Facebook should select if it is serious about creating an independent Supreme Court.

A Turkish sociologist and computer programmer, Tufekci was one of the first to raise the alarm about the moral and political dangers of social media platforms. She is a public intellectual of the internet age, using forums like the New York Times and Harvard’s Berkman Center to denounce Silicon Valley’s failure to be accountable for the discord it’s fostered. Tufecki has also taken aim at Facebook’s repeated use of “the community“—a term that is meaningless to describe 2 billion users—to defend its policies.

An iconoclast who has built several public companies, Thiel is also a lawyer who started the venture capital firm Founders Fund. A gay conservative and a supporter of Donald Trump, Thiel is deeply unpopular with Silicon Valley’s liberal elites—which is why his appointment would ensure ideological diversity on Facebook’s Supreme Court. Thiel is an early investor in Facebook and a longtime board member, which gives him a deep knowledge of the company. He would have to give up these positions to preserve the body’s independence.

Judge Lucy Koh

Koh has presided over numerous high-profile technology trials and is highly regarded in Silicon Valley. Her work as a federal judge includes the long-running patent trial between Apple and Samsung, as well as a case involving an antitrust conspiracy between Google, Adobe, and other firms. Her work on the bench and inspiring personal biography made her the subject of a flattering 2015 Bloomberg profile. Koh’s familiarity with the political and legal strategies of tech giants would provide invaluable expertise for Facebook’s Supreme Court (provided federal ethics rules permitted her to do so).

Tim Berners Lee

Sir Berners Lee is a computer science professor at Oxford University and MIT, who is best known as the inventor of the World Wide Web. Highly regarded in tech circles for his humility and vast knowledge, Berners Lee in recent years has become a vocal critic of the advertiser-based business models of the Silicon Valley tech giants. Appointing him to Facebook’s Supreme Court would show the company is serious about fixing its systemic problems with privacy.

Saint John, who was raised in Ghana, became a familiar name in tech circles when she became Apple’s head of music marketing after the company acquired her former employer Beats. She also worked at Uber before moving to the talent agency Endeavour. Saint John’s outspoken views on Silicon Valley’s white male culture would help inform Facebook’s Supreme Court in tackling hard issues of diversity.

Instagram users have been asking for a way to view all the data the company has on them, but this may be more than they were hoping for. The new Download Your Data tool that allows users to receive that information may have left some users’ passwords exposed.

When using the new feature, some Instagram users’ passwords were displayed in the URL, which was then also stored on Facebook’s servers—a bigger issue for those using a shared computer or compromised network, according to The Information. Facebook already notified users who were affected.

The tool has since been updated and the problem should no longer occur. Those Instagram users affected are encouraged to change their passwords and clear their browser history.
